On the residential side we repair, replace and install flat roofs on houses, rear additions, garages, laneway builds and rooftop decks, including the low-slope back roofs found on almost every Toronto row house. On the commercial side we handle plazas, industrial units, low-rise apartment and condo buildings and institutional roofs, from single-ply TPO through to two-ply modified bitumen. Flat roofs are the whole business: we do not quote shingles, siding or eavestrough. ## Sitemaps [XML Sitemap](https://flatroofstoronto.ca/sitemap_index.xml): Includes all crawlable and indexable pages.
